1T0 alL-whom it mag cian/eerie" Be it known that I, CHRISTIANLnsnais'rna,

a subject of the GerinanEmperor, residing at AiXJa-BhapeIIe, Germany,have invented a Q 5 certain new and useful Improved Roofing Tile, (forwhich I have obtained a patent in. Germany, No. 69,029 hearing dateSeptember 2, 1892, and in Belgium, No. 104,808, datedJune 15, 1893;) andI do'hereby declare to thatthe following'isa full, cle'hnand exactdescriptionot theinvention; which will enable others skilled in the artto which it appertains to make-and use the same. r

' This invention relates to an improvement :5 in ribbedan d grooved orinterlocking roof ttiles .and the. object of the invention is to,

. more thoroughly prevent water or snow being dr-ivenz-by the yvindthrough the roof and also to prevent deposited or percolating water 2ofromdripping do'wn from theunderside of the tiles. This object isattained inthe man ner shownjnthe drawings,in which-- Figure '1 is a topview andFig2 an underneath view vofwthe tile of this invention.

ais arecess and b a ridge on an upper edge of the' tile. Fromtheridge 1) (Fig. 1)

-'3o thereextend branch ridges c, d; for some distance atranysuitabletangle thereto and then parallel therewith. On the; undersnrfaeeof theopposite edge of the tile there are coveringgroovesformedby a recess e (Fig; 2) and 35 ridgesf; g,similarto ridges 0, (Landarranged symmetrically{therewith so that when the edgeof one 'tile isplaced tooverlap the edge of another; the ridges of the one tile lookinto the correspondingreoess of the other as shown 0 in dotted. lines inFig. 1. In this way any watertorsnow driven' by' the windinto recess ahastotravel a longer-distance and in a moreupwardly inclined direction;than is the case with single ridgeinterlocking tiles. At 5 all: the:places on theunder "side of the tile where water cancollect the tilesare provided in a suitable manner with sharp discharging edgesHFigs. 2,3, and 4); which are so formed and arranged that any water flowing downthem is discharged into a-discharge gutter it 5r or into a channell(Figs. 1 and 4), and thence on to the top of the roof. 1 E x In the caseof ordinary ribbed-roofing tiles having straight grooves formed byridges located parallel with the edges oftlie same the 5 5 water fallingnpona roof made of "suchtiles and penetrating into the space betweenany-two juxtaposed tiles, is carried ofl? along the grooves -and in windyand rainy onsnowy' V weather, water or snowis frequently driven 6b overthe ridge and underneath thereof. With my improved tile this. evil isremoved.

In'order to facilitate the movements ot'the workman whenlaying thetiles; those above. the lower layers are provided with a recess 0 .65

formed in the ridge n separating the chan nels m. This recess aifords ahold for the" workman;

What I claim asmyinvention, and desireto secure by Letters Patent, is- I70 1. On the upper side of interlockingroof tiles, the ridges cbranching angularlyfrom' the ridge b on the long edge of the tile intoarecess or channel a and having extensions f (1 parallel with ridge 1),said ridges c, d, being" 75 symmetrical with and of a similar shape toridgesfig in the covering recess or channel .e on the under side and atthe opposite edge of the tile, for the purpose specified, substantiallyas described and shown.
